From a Saratoga template perspective, both 1.9.4 and MX work to create the tags, realtime and NOAA report files needed.
The main difference is that MX does not create .png graphs for the wxgraphs page.. only 1.9.4 does. You can use JPGraph to create the graphs from the JSON available from MX (or use Highcharts JS to create from the JSON directly).
